[Message part 1 (text/plain, inline)]

In GuixSD:

guix package -i xterm strace
strace xterm

xterm starts as it should,  however observe many failed calls similar to:
 open("/gnu/store/b484nvn9nnr3ddclpz2fma9yxmimg2jj-fontconfig-2.11.94/lib/libXdmcp.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)


Now in the xterm, hold down Ctrl and press any mouse button.
The xterm aborts with the following messages:
 Warning: Unable to load any usable ISO8859 font
 Error: Aborting: no font found

Pressing Ctrl with any mouse button displays menus for me without any
error.  Did you install any font in your profile?  Try for example,
"guix package -i font-dejavu".  Perhaps you will also need to run
"fc-cache -f".

To make Xterm use a font I want, I have these lines in my ~/XTerm (it
can also be placed in ~/.Xresources I think):

XTerm*faceName: DejaVu Sans Mono
XTerm*faceSize: 12

     error.  Did you install any font in your profile?  Try for example,
     "guix package -i font-dejavu".  Perhaps you will also need to run

So that means that font-dejavu should be an input of xterm.  Shall I make that
change?

     XTerm*faceName: DejaVu Sans Mono
     XTerm*faceSize: 12
     

Presumably there is a default font which should work without any resource explicitly set?

I have no idea :-) I don't know why you get that error and how to fix
it, I just made a guess.

Same here.

Xterm uses server-side font rendering, so this cannot be a Fontconfig
issue.  Could it be related to 9eb5a449eed7297fdc2e6f3e77c2f625b07fddd1?

‘strace xterm’ suggests that xterm queries Xft, and eventually bails
out:

Strangely, “guix environment --ad-hoc xlsfonts -- xlsfonts” does work
and lists many fonts.

Thoughts?

I don't see how it could be related.  That commit didn't remove
anything, it just added "share/fonts/truetype/fonts.{dir/scale}" files
to guix profiles.

Fwiw, I see the same problem with 'xterm' on both of my GuixSD laptops,
on mips64el and i686.  The i686 laptop is running a full GNOME desktop
environment, and the mips64el laptop runs a somewhat minified Xfce
environment.

I remember that 'xterm' worked for me in the past, and specifically that
the pop-up menus raised by Ctrl-clicks worked, on both of these
machines.  However, at some point in the distant past I switched to
gnome-terminal, so I'm not sure when 'xterm' became broken.

OK, apparently it's broken by default since you all have this problem.
I think I just have some settings on my system that make it work
properly.  For example, I start X server with all font paths that I
need (I don't use SLIM), not sure if it relates.

"xset -q" gives me:

...
Font Path:
  <profile>truetype,<profile>X11/misc,<profile>X11/100dpi,<profile>X11/75dpi,built-ins

where <profile> is my guix profile with fonts.

Also I don't use 'font-alias' package, instead I use a "pure"
modification of it as described at
<https://lists.gnu.org/archive/html/bug-guix/2015-12/msg00022.html>.

But, well, I have no idea why xterm menus work for me :-)

I can reproduce this on GuixSD (foreign distros are OK).

By going to tty0 (Ctrl-Alt-F1) we can see the following text which gets
output at every crash:

--8<---------------cut here---------------start------------->8---
Warning: Unable to load any usable ISO8059 font
ERROR: Aborting: no font found

Apparently there is a patch which might fix that problem, available

I solved this issue by:

  - Install a font-misc-misc as Mike Hunt from Gentoo forum suggests¹:

    $ guix package -i font-misc-misc

  - From "(guix) Application Setup"²:

    $ xset +fp ~/.guix-profile/share/fonts/X11/misc


I wonder could we do this automatically after installing XTerm?

Good catch, it was just forgotten. Would you like to work on the suggestions
Ludovic gave John? It's unlikely that John will work on them after John
more-or-less left Guix.

Just to mention: I have font-misc-misc and some other fonts in my
profile with the Xorg font path set accordingly.  Apparently, that's why
I didn't experience this bug :-)

Oh, good to know!

We can also fix this once and for all with this patch:

I’ll go ahead and push that if there are no objections.
